(d) Start the engine and keep it running for 5 minutes after the water temperature goes up to above 80ć, then stop
the engine and completely drain the clean water in the cooling system.
Caution: If the discharged water is still dirty, clean the cooling system again according to the above steps
until discharged water becomes clean.
(4) After cleaning, tighten the water drain cock on the radiator. Apply Loctite 515 sealing glue to the water drain plug
on the engine and tighten it to 25 N·m.
(5) Add coolant. Fill the cooling system with the specified coolant, and the total volume is as follows:
Caution: Engine coolant capacity listed above refers to the coolant volume in the engine cooling system
only. The actual amount should refer to the vehicle or equipment data.
Caution: Add coolant slowly to avoid air block. Coolant should be added up to the bottom of the filler in the
radiator or meet the requirement of vehicle or equipment manufacturer. Wait for about 3-5 minutes for a full
purge of air.
(6) Install the pressure cap on the radiator, start and run the engine until coolant temperature goes up to 80ć, then
stop the engine and check the cooling system for leakage.
(7) Stop the engine and wait until the coolant temperature falls to below 50ć. Then slowly open the pressure cap and
recheck the coolant level. Supplement properly, if necessary.
4.3.25 Replacing air filter element (paper element)
Clean the inside of the filter body with pressured air. Check the new filter element for any defects and remove the
covering stuff from the compressor inlet. Install the new element and make sure a sound seal at both ends. Install the
air filter cover and the service indicator.
Caution: Be sure that both end faces of the air filter are reliably sealed without leakage after the air filter
element has been changed.

(1)Blow off dirt on the filter with pressured air.
(2)Remove the filter cover, remove and scrap the element.
Cover the compressor inlet from inside the air filter body
with clean stuff to prevent dirt from entering the intake
system.
